Technical Field

[0001] The present application relates to the field of electrophoresis devices, and in particular to a sliding skid device. Background Art

[0002] With the rapid development of economy, the number of people using cars is increasing. A car needs to go through processing, handling and assembly steps to become a complete vehicle that can be operated, including the assembly line process of painting, drying and final assembly. In this process, the movement of the car body is achieved by a skid. The skid is one of the necessary equipment for moving the workstations of the automobile body. It is slidably connected to the skid base and is powered by a power mechanism to complete the transportation of the car body.

[0003] The existing skids are generally equipped with four fixing points to meet the fixing and conveying requirements during the electrophoresis process. However, the skids can only be used for electrophoretic coating of one automobile part at a time. Therefore, for the existing automobile chassis, multiple parts of the chassis need to be electrophoretically formed in batches, which reduces the cycle time and affects the performance of the automobile. Therefore, how to meet the coating requirements of multiple parts of the automobile chassis has become an urgent problem to be solved. Utility Model Content

[0015] In some embodiments, the setting position of the support member on the skid body along the first direction is adjustable to standardize the coordinates of the limit member and the support surface, so as to meet the needs of multiple skateboard chassis sharing the same skid device and improve the applicability of the skid device.

[0016] In some embodiments, a connecting hole is provided on the supporting surface of the bracket, and the limiting member includes a rotating shaft and a positioning pin. The rotating shaft is passed through the connecting hole and its end protrudes out of the connecting hole. The positioning pin is provided at the protruding end of the rotating shaft. In the second direction, the axis of the positioning pin is eccentrically arranged relative to the axis of the rotating shaft; wherein the rotating shaft can rotate around the second direction in the connecting hole, and during the rotation of the rotating shaft, the positioning pin can change its position relative to the bracket and form a clamping surface arranged opposite to the supporting surface, thereby realizing the support and fixation of the electrophoretic component to be treated.

[0017] In some embodiments, both ends of the rotating shaft protrude from the connecting hole, and a positioning pin is provided at one end, and a shift plate is provided at the other end.

The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0031] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the embodiments of the present application should have the common meanings understood by technicians in the field to which the embodiments of the present application belong.

[0033] In addition, the technical terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0034] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0035] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0036] The skateboard chassis, also known as the CIIC integrated intelligent chassis, integrates the battery, electric drive system, suspension, brakes and other components on the chassis in advance to separate the body and chassis and decouple the design. The skateboard chassis mainly includes three separate assemblies: the front cabin, the box and the rear floor. After preparation, the whole electrophoretic coating is required to realize the assembly and molding of the skateboard chassis.

[0037] Referring to the current electrophoresis of complete vehicles and parts, there are mainly two electrophoresis schemes.

[0038] One is the whole vehicle skid technical solution, which selects four fixed points at the bottom of the vehicle body to meet the needs of fixation and transportation during the electrophoresis process. However, since the slide chassis can include three sub-assemblies, the four fixed points selected by the current skid device according to the whole vehicle electrophoresis process cannot meet the needs of fixing the three sub-assemblies during the electrophoresis process, so it is impossible to electrophoresize the three sub-assemblies at the same time, and the three sub-assemblies can only be electrophoresed in batches. However, batch electrophoresis will lead to a decrease in cycle time, resulting in increased energy consumption, working hours and manufacturing costs.

[0039] The other is the accumulation chain hanging electrophoresis, which realizes electrophoresis by hanging three sub-assemblies vertically. However, due to the complex structure of the three sub-assemblies, the vertical hanging electrophoresis method will cause gas accumulation in many places in the inner cavity of the three sub-assemblies, and air chambers will be generated during the vertical hanging electrophoresis process, resulting in electrophoresis quality problems, leading to subsequent corrosion problems, and the subsequent coating process needs to be disassembled and reassembled, which increases the complexity of the work.

[0040] Therefore, the current electrophoretic solution cannot meet the needs of low-cost, high-quality electrophoretic coating and its coating process for skateboard chassis. Based on the above considerations, the applicant has conducted in-depth research and proposed a new skid device. The skid device of the embodiment of the present application is further described below in conjunction with the accompanying drawings.

[0041] See also Figure 1 and Figure 2 The sled device 10 provided in the embodiment of the present application is configured to support multiple items to be electrophoretically processed. The sled device 10 includes a sled body 1 and a support structure. The sled body 1 extends along a first direction X. The support structure is arranged on the sled body 1. The support structure includes a plurality of support groups 2 spaced apart along the first direction X. Each support group 2 includes a plurality of support members 21. Each support member 21 is arranged to protrude from the sled body 1 along a second direction Z. The second direction Z intersects with the first direction X. Each support group 2 is configured to support one of the items to be electrophoretically processed.

[0042] The sled device 10 in the embodiment of the present application includes a sled body 1 and a support group 2, wherein the support group 2 includes a plurality of support members 21, so that the electrophoretic parts to be stably supported by the plurality of support members 21 of the same support group 2. The number of the support groups 2 is more than two, and they can be arranged on the sled body 1 at intervals along the first direction X, so that the sled device 10 can be used to support and fix the plurality of electrophoretic parts to be electrophoretically coated, so as to meet the requirements of synchronous electrophoretic coating of the plurality of electrophoretic parts to be electrophoretically coated, and there is no need to convert the sled device 10 multiple times during the coating process, so as to reduce the manufacturing time and realize the electrophoretic coating of multiple parts of the automobile chassis with high quality.

[0043] Optionally, the center line of the orthographic projections of the plurality of support members 21 of the same support group 2 in the second direction Z is generally polygonal, so as to achieve more stable support for the electrophoresis object.

[0044] It can be understood that the center lines of the positive projections of multiple support members 21 of the same support group 2 in the second direction Z are polygonal as a whole, which means that the support members 21 are distributed along multiple directions to ensure that the positive projection of the center of gravity of the electrophoretic component to be electrophoretically moved in the second direction Z is located within the skid body 1, so as to meet the requirement of the support group 2 for stable support of the electrophoretic component.

[0045] The specific arrangement position and number of the support members 21 are related to the structures of the sled body 1 and the electrophoretic object. As an example, when the sled body 1 includes a first longitudinal beam 11, a second longitudinal beam 12 and a cross beam 13 connecting the first longitudinal beam 11 and the second longitudinal beam 12 which are arranged relatively along the third direction Y, the number of the support members 21 can be set to four, two of the four support members 21 are arranged on the first longitudinal beam 11, and the other two are arranged on the second longitudinal beam 12, and the center line of the orthographic projections of the four support members 21 in the second direction Z can be rectangular, thereby forming four fixed points to support the electrophoretic object.

[0046] Alternatively, the number of support members 21 can also be set to six, wherein three of the six support members 21 are arranged on the first longitudinal beam 11, and the other three are arranged on the second longitudinal beam 12, and the center line of the positive projections of the six support members 21 in the second direction Z can be rectangular, thereby forming six fixed points to support the electrophoretic component.

[0047] Optionally, the number of support members 21 of multiple support groups 2 may be the same or different. For example, among multiple support groups 2, some support groups 2 may be provided with four support members 21, while another part of the support groups 2 may be provided with six support members 21. That is, the number of support members 21 may be adjusted according to the structure of the electrophoretic component to be electrophoresed, so as to meet the need to support multiple electrophoretic components.

[0048] It should be noted that the skid device 10 in the embodiment of the present application is used to support multiple parts to be electrophoresed, and it can be used to support the skateboard chassis in the vehicle body, and can also be used to support other parts of the vehicle body.

[0049] See also Figures 1 to 3 For the electrophoretic coating of the skateboard chassis, in some optional embodiments, the number of the support groups 2 is more than three, and the multiple parts to be electrophoretically coated include at least one of the front floor assembly 20, the chemical chamber assembly 30 and the rear floor assembly 40.

[0050] By setting more than three support groups 2, the three sub-assemblies of the front floor assembly 20, the chemical chamber assembly 30 and the rear floor assembly 40 in the skateboard chassis can be supported at one time to meet the coating process requirements of the three sub-assemblies such as electrophoresis, body sealing, body bottom glue sealing, damping pad installation, wax injection, etc. On the one hand, it can eliminate the problem of gas accumulation in the process of electrophoresis using the accumulation chain hanging method and improve the quality of electrophoresis. On the other hand, compared with the existing skid device 10, it can improve the electrophoresis rhythm to reduce the energy consumption and manufacturing cost of the electrophoresis process.

[0051] For ease of description, the following description will take the skid device 10 as including three support groups 2, each support group 2 including four support members 21, and supporting three sub-assemblies of a skateboard chassis as an example.

[0052] See also Figures 1 to 3 In some optional embodiments, among the multiple support groups 2, the support members 21 of at least two support groups 2 have a difference in the protruding distance relative to the skid body 1 along the second direction Z, so that after the sub-assemblies are transferred and hung on the skid device 10, there can be a certain height difference between the sub-assemblies in the second direction Z, thereby meeting the subsequent coating process requirements such as glue sealing, cover installation, and wax injection at one time.

[0053] It can be understood that, due to the different structures of the sub-assemblies, in order to ensure the horizontal arrangement of the sub-assemblies, the sizes of the support members 21 in the same support group 2 along the second direction Z may differ, so the protruding distance of the support members 21 of the support group 2 relative to the skid body 1 along the second direction Z refers to the average value of the protruding distances of the multiple support members 21 of the same support group 2 relative to the skid body 1 along the second direction Z. Therefore, by making the average values ​​of the protruding distances of the support members 21 of the multiple support groups 2 differ, the multiple sub-assemblies can have height differences in the second direction Z, thereby meeting the subsequent painting requirements.

[0054] Optionally, for the three sub-assemblies of the skateboard chassis, when the number of support groups 2 is three, the protruding distances of the support members 21 of any two support groups 2 in the three support groups 2 relative to the skid body 1 along the second direction Z can be different, so that after the sub-assemblies are transferred and hung on the skid device 10, the three sub-assemblies have no overlap in the second direction Z, so as to meet the implementation requirements of the subsequent coating process.

[0055] Among them, the three support groups 2 arranged at intervals along the first direction X are defined as the first support group 2a, the second support group 2b and the third support group 2c, so that the protruding distance of the support members 21 of the second support group 2b relative to the skid body 1 along the second direction Z can be smaller than the protruding distance of the support members 21 of the first support group 2a and the third support group 2c relative to the skid body 1 along the second direction Z. The above arrangement can make it possible that within the same support range, there is a larger support span along the second direction Z between the adjacent first support group 2a and the second support group 2b, and between the second support group 2b and the third support group 2c, which is more convenient for the subsequent painting of the skateboard chassis.

[0056] See also Figures 1 to 3 In some optional embodiments, the support member 21 includes a bracket 211 and a stopper 212, the bracket 211 forms a support surface that is set away from the sled body 1, the stopper 212 is connected to the support surface and is used to fix the electrophoresis object, and the size of the bracket 211 along the second direction Z is adjustable. Therefore, the size of the bracket 211 along the second direction Z can be adjusted according to actual needs to adjust the position of the support surface along the second direction Z, so as to adapt to the subsequent painting of the skateboard chassis of more models of vehicles, thereby improving the applicability of the sled device 10.

[0057] It is understandable that the position of the limit member 212 needs to be compatible with the positioning hole of the sub-assembly. Therefore, in some optional embodiments, the bracket 211 includes a first support arm 2111 and a second support arm 2112 that are arranged to intersect each other. The first support arm 2111 is connected between the skid body 1 and the second support arm 2112. The limit member 212 is arranged on the side of the second support arm 2112 away from the first support arm 2111. The second support arm 2112 can be at least partially retracted to adjust the minimum vertical distance between the limit member 212 and the first support arm 2111.

[0058] By making the second support arm 2112 at least partially retractable, the length of the second support arm 2112 and the position of the limit member 212 can be adjusted according to actual needs, so that the sled device 10 can support different types of electrophoretic objects, further improving the applicability of the sled device 10.

[0059] Optionally, the first support arm 2111 and the second support arm 2112 may both be configured as telescopic rods, the first support arm 2111 extends along the second direction Z, and the extension direction of the second support arm 2112 intersects with the extension direction of the first support arm 2111. For example, the second support arm 2112 may extend along the first direction X or along the third direction Y. The telescopic rod may be driven hydraulically or electrically, and the sizes of the first support arm 2111 and the second support arm 2112 may be adjusted.

[0060] Furthermore, the support member 21 further includes a base 213, the base 213 is disposed on the sled body 1, the first support arm 2111 is rotatably connected to the base 213, and the rotation axis of the first support arm 2111 is disposed along the second direction Z. That is, the first support arm 2111 is connected to the sled body 1 through the base 213, and by rotatably connecting the first support arm 2111 to the base 213, the position of the limit member 212 can be adjusted within a circumferential range with the first support arm 2111 as the axis and the longest dimension of the second support arm 2112 as the radius on the basis of the adjustable second support arm 2112, so as to further improve the applicability of the sled device 10 and realize the support and fixation of different sub-assemblies.

[0061] In addition, in some optional implementations, the setting position of the support member 21 along the first direction X on the skid body 1 is adjustable, so as to further improve the degree of freedom of the limit member 212, so as to standardize the coordinates of the limit member 212 and the supporting surface, meet the needs of multiple skateboard chassis models sharing the same skid device 10, and improve the applicability of the skid device 10.

[0062] Optionally, a plurality of adjustment holes may be provided at intervals along the first direction X on the sled body 1, and the positions of the support members 21 along the first direction X may be adjusted by detachably connecting the support members 21 to the adjustment holes. Alternatively, a slide rail extending along the first direction X may be provided on the sled body 1, and a slider adapted to the sled body 1 may be provided on the support member 21 to achieve position adjustment of the support member 21 on the sled body 1, that is, the position adjustment requirement of the support member 21 on the sled body 1 may be met.

[0063] It is understandable that the second support arm 2112 can be extended along the third direction Y to increase the adjustment range of the limiter 212. According to the actual size range of the sub-assembly, only the setting position of the support member 21 along the first direction X can be adjusted, or only the second support arm 2112 can be retracted along the third direction Y, or the second support arm 2112 can be retracted along the third direction Y on the basis of making the setting position of the support member 21 along the first direction X adjustable. In addition, the adjustable ranges of the support member 21, the first support arm 2111, and the second support arm 2112 can be adjusted according to the sub-assembly of various models of vehicles.

[0064] See also Figure 2 , Figure 4 and Figure 5 In order to fix the electrophoretic element, in some optional embodiments, a connection hole is provided on the support surface of the bracket 211, and the stopper 212 includes a rotating shaft 2121 and a positioning pin 2122. The rotating shaft 2121 is passed through the connection hole and its end protrudes from the connection hole. The positioning pin 2122 is provided at the protruding end of the rotating shaft 2121. In the second direction Z, the axis of the positioning pin 2122 is eccentrically arranged relative to the axis of the rotating shaft 2121. The rotating shaft 2121 can rotate around the second direction Z in the connection hole, and during the rotation of the rotating shaft 2121, the positioning pin 2122 can change its position relative to the bracket 211 and form a clamping surface arranged opposite to the support surface.

[0065] It is understandable that by arranging the axis of the positioning pin 2122 to be offset relative to the axis of the rotating shaft 2121, when the rotating shaft 2121 rotates in the connecting hole, the positioning pin 2122 will change its position relative to the bracket 211 to satisfy the rotation or clamping function.

[0066] Specifically, the support member 21 includes a rotating hanging state and a clamping state, and the support member 21 can be switched between the rotating hanging state and the clamping state by driving the rotating shaft 2121 to rotate relative to the bracket 211.

[0067] In the rotation state, the orthographic projection of the locating pin 2122 on the bracket 211 along the second direction Z is located within the orthographic projection of the locating hole of the sub-assembly on the bracket 211, and the body locating holes of each sub-assembly of the skateboard chassis can cooperate with the locating pin 2122 and be rotationally hung on the bracket 211 along the second direction Z.

[0068] In the clamping state, the orthographic projection of the locating pin 2122 along the second direction Z on the bracket 211 is at least partially offset from the orthographic projection of the locating hole of the sub-assembly on the bracket 211, so that a clamping surface arranged opposite to the supporting surface can be formed by the locating pin 2122 to lock the sub-assemblies of the skateboard chassis between the supporting surface and the clamping surface, thereby limiting the movement freedom of the sub-assemblies of the skateboard chassis along the second direction Z to achieve positioning support of the skateboard chassis.

[0069] Optionally, the bracket 211 further includes a pin sleeve 2113 fixedly connected to the second support arm 2112, the pin sleeve 2113 coincides with the axis of the rotating shaft 2121, and a support surface is formed at the end of the pin sleeve 2113. By providing the pin sleeve 2113 on the bracket 211, the subassembly can be overlapped on the pin sleeve 2113, thereby improving the structural strength of the bracket 211, improving the supporting force, and increasing the service life of the support member 21.

[0070] In order to facilitate the rotation of the rotating shaft 2121, in some optional embodiments, both ends of the rotating shaft 2121 are protruded from the connection hole, and a positioning pin 2122 is provided at one end, and a dial plate 2123 is provided at the other end, and the dial plate 2123 is fixedly connected to the rotating shaft 2121. By connecting the dial plate 2123 to the other end of the rotating shaft 2121, the rotating shaft 2121 can be driven to rotate by the dial plate 2123, so as to realize the switching of the support member 21 between the hanging state and the clamping state.

[0071] The following is an example of the three sub-assemblies of the skateboard chassis. Figures 1 to 5 The conveying steps of the sled device 10 in the embodiment of the present application are described.

[0072] During the product design stage, corresponding support groups 2 are provided on the skid device 10 according to the positions of the three sub-assemblies, and each support group 2 is provided with a plurality of support members 21 to achieve coordinated support of each sub-assembly.
